Invention of high-performance, environmentally friendly disazo acid dyes (D1-D4) intended for sustainable textile coloring and pH-responsive sensing applications is reported in this study. Sulphanilic acid and other aromatic derivatives were used in simplified diazotization-coupling procedure to create dyes. Effective integration of azo and sulfonate groups, guaranteeing superior water solubility, was verified by structural characterization. Dyes created bright, high-affinity orange and red colors with remarkable wash and light fastness (ratings: 4–5) when applied to wool and nylon. λmax values in UV-vis spectra varied according to substituent location, from 479 to 485 nm. Notably, protonation-deprotonation balance drives Dye D1’s reversible, “smart” color shift from brown to pink in response to pH changes. Among synthesized dyes, D1 showed a clear and reversible pH-responsive color change, going from brown to pink under increasingly acidic conditions, while D3 showed mild pH sensitivity and dyes D2 and D4 remained color-stable throughout tested pH range of 2–4, displaying distinct chromatic stability profiles. Compared to nylon, the K/S and fastness qualities of wool materials were higher. These results show that synthesized dyes have great promise for creation of novel, pH-sensitive smart fabrics in addition to offering excellent technical performance and high fixing, which reduces environmental leaching.
Water contamination by hazardous organic dyes and nitrophenols, particularly methylene blue (MB) and 4-nitrophenol (4-NP), is one of the critical environmental challenges in recent times. Conventional remediation methods often face limitations, including inefficiency, high cost, and the generation of secondary pollution. Catalytic reduction using metal/metal oxide (M/MO) nanoparticles (NPs) is a promising alternative for converting these pollutants into less harmful substances. However, the practical application of bare M/MO NPs is hindered by issues of aggregation, instability, and leaching. This paper comprehensively discusses the innovative strategy for stabilizing M/MO NPs with eco-friendly and cost-effective biopolymers. The paper explores strategies for extraction of biopolymers, synthesis and characterization of biopolymer-stabilized M/MO nanocomposites (NCs), their effectiveness in reducing 4-NP and MB, their stability and reusability, as well as the mechanisms of the reduction process. Furthermore, the critical operational parameters influencing catalytic efficiency are discussed, and performance is evaluated through key catalytic performance metrics such as the conversion rate, rate constant, and turnover frequency. The finding of the review revealed that biopolymer incorporation into M/MO NPs significantly enhanced MB and 4-NP conversion efficiency while improving nanoparticle dispersion, stability, and reusability. Despite their considerable advantages, challenges such as potential nanoparticle leaching, biopolymer degradation, and the need for reducing agent optimization remain. The review finally presents future research directions, which include the development of greener alternatives to NaBH4, computational mechanistic studies, and scaling up the technology for real-world wastewater treatment applications.
Coagulation-flocculation is one of the widely used techniques for removing toxic dyes from the contaminated water and wastewater due their effectiveness in dye removal. The high costs, large volume of sludge generation and potential health effects of the conventional chemical coagulants/flocculants necessitates searching for cost-effective, less toxic and eco-friendly alternatives. This study investigates the potential of M. oleifera seed and O. ficus indica cladodes in removing CR dye from the aqueous phase using the coagulation-flocculation technique. The plant materials were extracted using 0.5 M CaCl2 and characterized by FT-IR, proximate and elemental analyses. Additionally, the experiment was optimized to study the influence of the process parameters, including pH, M. oleifera/O. ficus-indica dosages, initial concentration of CR dye, and settling time. The findings of the study revealed that the combined applications of oleifera seed and O. ficus indica cladodes achieved 98.7% CR removal rate under optimized conditions. The performance of the plant-based materials was found to be statistically comparable to that of the conventional chemical coagulant (alum) with more than 4 times less sludge volume generation. FT-IR, proximate, and elemental analysis revealed the presence of proteins and polysaccharides as the key bioactive compounds responsible for the charge neutralization and bridging mechanisms, respectively. This research demonstrates the effectiveness of M. oleifera seed and O. ficus-indica cladodes in the coagulation-flocculation process, offering a cost-effective and environmentally friendly alternative to conventional water and wastewater in line with UN sustainable development goals strategies.
Metal–organic frameworks (MOFs) are crystalline porous materials composed of central metal ions coordinated to organic ligands, forming tunable frameworks. Due to their excellent textural properties and superior mechanical and thermal stability, pristine MOFs have been utilised as electrode materials for electrochemical capacitors. Nevertheless, the limited electrical conductivity negatively affects their rate performance. Herein, we report the enhanced capacitance properties of Ni-based MOF/rGO composite prepared by a facile in situ method with a low loading level of rGO. The microstructural studies revealed that the presence of the GO in the reaction bath not only influences the morphology of MOF but also facilitates the transformation of the nickel salt precursor into the final product. The optimised Ni-MOF/rGO2.0 electrode exhibited a specific capacity of 527 C g⁻1 at 6 A g⁻1 as compared to pristine Ni-MOF (402 C g⁻1). Furthermore, Ni-MOF/rGO2.0 electrode demonstrated a superior rate capability by retaining 38.11
The pervasive introduction of toxic substances into the environment poses significant threat to human health and ecological integrity, driving the urgent need for sustainable remediation technologies. Biosurfactants, derived from microorganisms, are emerging as powerful and eco-friendly alternatives to synthetic surfactants, offering viable pathway for effective environmental management. This review highlights the remarkable versatility of biosurfactants in combating pollution challenges, including soil waste water detoxification, oil spill recovery, and heavy metal sequestration. Their efficacy stems from unique properties such as high biodegradability, low toxicity, ability to enhance the bioavailability and biodegradation of hydrophobic pollutants through emulsification and micelle formation. Furthermore, we explore their promising antimicrobial and anti-biofilm properties, which open new frontiers in biomedical and environmental applications. Despite their immense potential, widespread adoption is hindered by challenges such as high production costs, yield inconsistency, and scalability issues. Overcoming these barriers necessitates advancements in microbial fermentation technologies and the strategic use of cost-effective feedstocks, like agricultural waste. This review concludes that biosurfactants hold transformative promise for pioneering a new era of sustainable remediation. Future efforts must focus on optimizing production processes to unlock their full potential for large-scale industrial and environmental applications, paving the way for a cleaner and more sustainable future.
